Abstract: The present invention provides two methods for configuring transmit power of sounding reference signal (SRS), a network device and a UE. One of the methods includes: with a network device, determining SRS transmit power parameters according to power level of signal previously sent from a UE received by each cell to be detected and/or information of cells to be detected by the UE, and sending the SRS transmit power parameters to the UE. The present invention can have an overall consideration on path losses of multiple cells to be detected when calculating the SRS transmit power. Therefore, the power of the cell having poor channel quality for receiving SRS can be guaranteed, in order to ensure the accuracy of channel estimation.

Abstract: A method and apparatus for reporting channel state information (CSI) based on a physical uplink shared channel (PUSCH) are used to realize correct reporting of the CSI based on double code books. The method includes the following steps: a reporting mode configuration signaling for the CSI sent from a network side is received, and said reporting mode configuration signaling for the CSI at least carries a designated reporting mode identifier; a first CSI aiming at the whole bandwidth of a system is established according to a reporting type corresponding to said reporting mode identifier; the whole bandwidth of the system is divided into at least two frequency band subclasses, and a second CSI aiming at a designated frequency band subclass is established according to the reporting type corresponding to said reporting mode identifier; and when a reporting indication signaling sent from the network side is received, said first CSI and said second CSI are transmitted to the network side. Therefore, when a user equipment (UE) reports the CSI, a long-term/wideband CSI and a short-term/frequency selective CSI could be considered comprehensively, then a two-level feedback mechanism based on the PUSCH double code books is realized.
